Kwikset 83347 158/780/816/980 RCAL Deadbolt, Round Corner Adjustable Latch, 2-3/8" or 2-3/4" Backset

One part covers both. The Kwikset 83347 deadbolt latch is adjustable between 2-3/8 inch and 2-3/4 inch backset, so you collapse or extend it on site to match the cross-bore location already drilled in the door. Those are the two standard residential and light commercial backsets, so a single 83347 handles either prep without a second order line.

The 83347 is the replacement deadbolt latch for Kwikset 158, 780, 816 and 980 deadbolts. If the deadbolt body on the door is one of those model numbers and the latch is worn, bent, or the wrong backset, this is the matching bolt assembly rather than a whole new deadbolt.

Round corner. The 83347 uses an RCAL (round corner adjustable latch) faceplate, so it drops into a door edge mortise that was routed with a radius corner, which is what a hinge and latch router template produces. If the existing mortise in your door is cut square, a round corner face will leave gaps at the corners and you want a square corner deadbolt latch instead.

No. The Kwikset 83347 is a deadbolt latch, meaning a dead-throw bolt driven by a thumbturn or key cylinder with no spring return and no beveled face for a latch to ride over a strike. For a knob or lever opening you need a regular spring latch, such as the Deltana G1RLE238 Grade 1 regular latch with an entry function on a 2-3/8 inch backset or the G1RLE275 in the 2-3/4 inch backset. For a non-keyed opening the Deltana G1RLP238 and G1RLP275 are the Grade 1 passage/privacy versions in the same two backsets.

The Schlage Commercial 12-289 is the nearest match in function and prep. It is a B500 Series deadbolt latch that adjusts between a 2-3/8 inch and 2-3/4 inch backset with a 1 inch by 2-1/4 inch face and a 1/4 inch round corner, the same adjustable-backset, round-corner deadbolt arrangement the Kwikset 83347 uses for its 158, 780, 816 and 980 deadbolts. Confirm the existing face plate dimensions in the door edge mortise before swapping, since the two are keyed to their own manufacturers' deadbolt bodies.

Kwikset classes the 83347 as a commercial latch, which is the right call for multi-family and light commercial unit doors carrying Kwikset 158, 780, 816 or 980 deadbolts. Because the backset adjusts between 2-3/8 and 2-3/4 inches, you can stock one part number across a building even where the door preps are not consistent.

A deadlatch has a beveled latch bolt with an anti-shim plunger and retracts with the knob or lever, which the Kwikset 83347 deadbolt latch does not do. The Schlage 16-480 is a deadlatch for the S200 Series that adjusts between a 2-3/8 inch and 2-3/4 inch backset with a 1 inch by 2-1/4 inch square corner face. The Dexter C1000-DL-630 is a Grade 2 deadlatch built for the C1000 Series.

The Kwikset 83347 is a replacement latch component for Kwikset 158, 780, 816 and 980 deadbolts, not a complete lock, so it does not by itself address a sidelite or an ADA operating requirement. For that opening, the Accentra YSSL10 is a security sidelite auxiliary latch with an ADA compliant thumbturn, fire rated and built for a 1-3/4 inch door thickness.

Yes. The Kwikset 83347 is a service latch that goes back into an existing Kwikset 158, 780, 816 or 980 deadbolt and keeps the original key cylinder. If you would rather move the opening off keys entirely, the Lockey M230 is a mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, fitting doors 1-1/8 inch to 2 inch thick. Note the M230 uses a spring latch rather than a dead-throw bolt, so the strike and security behavior differ from a deadbolt.

Polished brass is the finish offered on the 83347. Bear in mind the latch face is mostly hidden in the door edge once the strike side is closed, so the visible match that matters on a fleet of doors is the deadbolt rose and turn piece, not this part.

Treat the 83347 as the bolt assembly for Kwikset 158, 780, 816 and 980 deadbolts only. If the jamb strike is damaged or the frame prep is being moved, order a deadbolt strike separately, and confirm the strike corner style matches the frame mortise the same way the round corner face has to match the door edge mortise.
